one of the moods of a verb, used when we would command, intreat, or advise; thus, *go read*, *take pity*, *be advised*, are imperatives in our language. But in the learned languages, this mood has a peculiar termination to distinguish it from others, as *i*, or *ito*, "go"; *lege*, or *legito*, "read," &c., and not only so, but the termination varies, according as you address one or more persons, as *audi* and *audite*; *exules*, *exules*, *exiles*, &c.
